This paper analyses changes in the quality of meat (M. longissimus dorsi) of roe deer bucks during 21 days of cold storage (2 degrees C) under vacuum and modified atmosphere (MA) conditions (40% CO2/60% N2 and 60% CO2/40% N2). After 21 days of storage, meat packaged in a MA with 40% CO2 had higher (P < or = 0.05) L*, a*, b* and C* values in comparison with meat stored under vacuum and MA with 6...

In this study, the influence of different treatments was evaluated: nonwashing, washing in chlorinated water and washing/soaking in chlorinated water and sodium chloride on the quality of Nile tilapia (Oreochromis niloticus) fillets during storage at 1.0 ± 0.5°C through daily analysis of pH, moisture, and lipids content. Microbiological analysis and growth modeling for mesophilic and psychrotro...

Psychrotrophic bacteria of the genus Psychrobacter have not been studied in respect to lipopolysaccharide structure. In this work, we determined the structure of the O-specific polysaccharide of the lipopolysaccharide of Psychrobacter muricolla 2pS(T) isolated from overcooled (-9°C) water brines within permafrost. The polysaccharide was found to be acidic due to the presence of an amide of 2-ac...

In this study, the effect of lactococcin BZ on microbiological quality of fresh beef is investigated. For this purpose, the meat samples were treated with various amounts of lactococcin BZ (200-2500 AU/mL), a bacteriocin produced by Lactococcus lactis spp. lactis BZ, and kept at 4-5 °C for 12 days. During storage, the microbiological properties of the meat samples with or without lactococcin BZ...

The effect of commercial oxygen absorbers on sliced ham quality packaged in barrier film (OTR @ 60cc/m/da) under rigorous display conditions was investigated. Atmospheric pressure, vacuum, and CO2 back-flushed packaging methods were used. Color, microbial counts, lipid oxidation, and sensory odor were evaluated weekly over a period of 79 days in 10°C storage under fluorescent light. Ham contain...

This paper describes the complete genome sequences and methylome analysis of six psychrotrophic strains isolated from perennially ice-covered Lake Untersee in Antarctica.

Two experiments were conducted to evaluate the effect of chitosan as a biological sanitizer on chicken skin during storage. For experiment 1 (two trials) five skin samples of equal size were dipped into a solution containing 10 cfu/mL of Salmonella Typhimurium (ST) for 30s. Skin samples were then removed 6 and dipped into a solution containing PBS or 0.5% chitosan for 30s. In experiment 2, aero...
